To that end, the gage plate 26, in the present exemplification of the invention, is supported by three arms or links 21, 28, and 29. The arms or links 21 and 28are connected to a rod or shaft 30, that is journaled in suitable bearings 3i, and which rod or shaft is disposed in an inclined position, parallel with the plane of the rotary,

knife.

The arm 30 is pivotally connected :to the gage plate, preferably by passing between spaced earsv electric lamp 62 is disposed within the housing or bearings 32, and pivotally secured in position by a bearing pin 33. The arm or link- 21 carries a pin 34, having a conical end which engages in a conical bearing 35 of the frame structure 36 fixed Icy-friction, at any desired point of adjustfor the gage plate 26. The'portion'36 of the frame structure in which the conical bearing 35 is provided, is shaped to serve as a guard for the adjacent part of the knife edge, as well as for the armor link 21."

The arm or link 29 is secured or connected to a pin or shaft 31,'journaled in suitable bearings 38,

and carries a pin or projection 39, in an extended portion or leg 40 of the gage plate 26. This extended portion 40 of the gage-plate projects below the knife, and serves as a guard for guarding the knife at itsloweredge'. a r

The gage plate 26 may be adjusted to and from the cutting plane in any suitable manner, but preferably by means of a'hand grip 4|, of a bar 42, which bar isfixed to a horizontal bar or shaft 43, journaled'iri suitablebearings in the framework; and also in a housing 44, which housing, at

the front, is provided with projections 4-5, by. means of which it may be bolted or secured to the floor of the main frame by suitable fastening devices 46, such as bolts, screws, or the like.

The shaft 4?, carries a worm 41, which meshes with a worm wheel 48, carried by the bar or rod 30. At the other end of the shaft 43 is another worm (not shown),jwhich meshes with a worm wheel .49, carried bythe pinor'shaft 31. Thus, when the bar or rod 42 is actuated by th handle 4 l ,the rod or shaft 30 will be rotated through the medium of the intermeshing worm and worm wheel-41, 48. The rotation of the shaft 30,.will

also rotate the pin or shaft 31, through the medium of the'worm gear on the shaft meshing with the worm wheel 49 on the pin or shaft. This will v ,cause the gage plate26 to be 'moved'towards or away from the'cutting plane, according to the direction of movement of the bar or rod 42. If desired, springs 50, 51 may be provided, respectively, on the shaft 30 and pin or shaft 31, to compensate the clearance between the respective worms and worm gears.

. The usual knife mask 52 may be provided, and

bears, atits lower edge 53, upon the machine base, being held in position by means of pins or projections 54, secured to the base and passing into apertures in the base of the mask. The top side ,of the mask may be held in position by means of a fastening device, well known in this art.

of the machine, to facilitate reading the indication on the member 51.

, The hand grip 4| carries a spring pressed plunger 63, which permits the mechanism to be 'ment. A handle 64 is provided for reciprocating the carriage and the substance support. With this improved construction, the gage plate, and the means for supporting and adjusting it, are incorporated inthe machine as a unit, and as such is removable fromthe rest of the machine;

While the preferred form of the invention has been herein shown and described, it is to be understood that various changes may be made in the details of construction, and in the combination and arrangement of the several parts, within the scope of the claims, without departing from the spirit of this invention. What is claimed as new is:

' 1.In a slicing machine, a housing, a rotary slicing knife on a turning axis, a slice thickness gauge plate extending outwardly of the edge of said knife on one side of said axis, said knife and plate being disposed in inclined planes, a rock shaft disposed below said plate adjacent one edge thereof and journaled in bearings mountedon said housing, arms on the shaft pivotally connected to said plate, a rock shaft remote from the first said shaft, the last said rock shaft also being journaled in bearings mounted on said housing, an arm on the second said shaft, a leg extending outwardly from said gauge plat substantially parallel to the planes of the knife and gauge plate and beneath the knife to leave the Space beneath the gauge plate unobstructed by itsiadjusting mechanism, a pivotal connection between the last said arm and said leg, said arms engaging said plate at connecting points adjacent the edge of said knife and angularly spaced with respect to said turning axis, an intermediate shaft operatively connected to the first and second recited shafts, and an operating member connected to one of said shafts for rocking all of saidshafts to adjust said gauge plate. I

2. In a slicing machine, a housing, a rotary slicing knife on a turning axis, a slice thickness gauge plate extending outwardly of the edge of said knife on one sid of said axis, said knife and plate being disposed in inclined planes, a rock preferably constructed of glass, and which may begpartly, recessed into'the housing and partly project therefrom. At the front of this member, there is provided a series of indications, such as shaft disposed below said plate adjacent one edge thereof and journaled in bearings mounted on said housing, arms on the shaft pivotally connected to said plate, a rock shaft remote from the first said shaft, the last said rock shaft also being journaled in bearings mounted on said housing, an arm on the second said shaft, a, leg extending outwardly from said gauge plate substantially parallel to the planes of th knife and gauge plate and beneath the knife to leave the space beneaththe gauge plate unobstructed by its adjusting mechanism, a pivotal connection between the last said arm and said leg, said arms engaging said plate at connecting points adjacent the edge of said knife and angularly spaced with respect to said turning axis, an intermediate shaft operatively connected to the first and second recited shafts, and an operating member connected to one of said shafts for rocking all of said shafts to adjust said gauge plate, the connection between said shafts embodying gear elements. I

3. In a slicing machine, a housing, a rotary slicing knife on a turning axis, a slice thickness gauge plate extending outwardly of the edge of said knife on one side of said axis, said knife and plate being disposed in inclined planes, a rock shaft disposed below said plate adjacent one edge thereof and journaled in bearings mounted on said housing, arms on the shaft pivotally connected to said plate, a rock shaft remote from the first said shaft, the last said rock shaft also being journaled in bearings mounted on said housing, an arm on the second said shaft, 9. leg extending outwardly from said gauge plate substantially parallel to the planes of the knife and gauge plate and beneath the knife to leave the space beneath the gauge plate unobstructed by its adjusting mechanism, a pivotal connection between the last said arm and said leg, said arms engaging said plate at connecting points adjacent the edge of said knife and angularly spaced with respect to said turning axis, an intermediate shaft operatively connected to the first and second recited shafts, said shafts and the connections thereof with said gauge plate being disposed within the machine housing, and means accessibl from the outside of said housing for actuating said shafts.
